Part 3: Deep Dive – Reading the Wannien 101V0 Schematic

Let’s walk through a typical schematic found in a wannien 101v0 power supply schematic repack. We’ll assume the 12V/8A variant. High Resolution Photography: Take a photo of the

PWM Controller: Boards of this era often use standard PWM ICs (like the TEA1733T or NCP series) to drive the transformer. Repack / Repair Procedure

  1. High Resolution Photography: Take a photo of the top side (components) and bottom side (traces) at 300 DPI.
  2. Trace Mirroring: Using GIMP or Photoshop, mirror the bottom layer so it aligns with the top.
  3. Chase the PWM IC: Start at Pin 1 of the controller. Identify VCC (usually goes to a small cap and a startup resistor from the 300V rail).
  4. Redraw in KiCad or EasyEDA: Manually place components and draw nets. This is time-consuming but yields a perfect repack.
  5. Share Back: Upload your repack to repositories like ElektroTanya or Badcaps.net under the name "Wannien 101v0 Rev X Schematic Repack."

If your device has no power or a flickering display, the Wannien 101V0 board is the most likely culprit. Technicians frequently encounter these issues:

Capacitors: "No power" or "no display" symptoms are frequently caused by bulging or dried-out capacitors in the secondary output stage.
